MINOR: Add comment to onPartitionsLost override (#14121) 
This adds comments to the ConsumerRebalanceListener overrides, in order to briefly explain why we are overriding these methods, when they are called, and what you can or can't do. Especially onPartitionsLost can create some confusion given the default implementation.
